T0 ALL WHOM IT MAY CONCERN: y Y

Be itknnwn that I, DANIEL W. PEPPER, of Philadelphia, Pennsylvania,V have invented au improvement iu Metal Cans or Vessels; .and I do hereby declare the following to be' a full, clear, audexact description of the same, reference being had to the accompanying drawing, and to the-letters of reference marked thereon.

My invention relates to a mode of securing caps to metal cans or vessels for containing paints and other articles; and my`invention consists in making in the top of a vessel anopening edged with an annular iiange, 1

to whichis adapted a similar flange on the cap, ,the two ilauges being acted on in the manner described' hereafter, so as to be brought into intimate contact and e'ectually secured together.

i In order to enable others skilled in the art to make and apply my invention, I will now proceed to describe the manner of carrying it into elect, reference being had to the accompanying drawing, which forms a part'oi` this specification, and in whioh- Figures 1, 2, and 3 are sectional views of a metal can and cap, illustrating the manner in which the latter is secured to the former.

Figure 4 is a plan view of the can, with the cap-secured to the same; and

Figure 5, a perspective view. i

The body A of the can` consists of a casing of thin metal, to which 'are secured the top a and the bottom In the top ais an opening,x, the edge of the metal round the opening being bent upwards so as to form an annular flange, e. The capB consists of a disk of thin metal, the edge of which is turned downwards so as to form an annular ange, z', arranged to t snugly over the ange e of the top a, and in the upper surface of the latter is a circular depression or recess; y. After the can has been filled the cap B is applied, as shown' in iig. 2, so as to cover the opening x, after which the can is placed on, and secured to, a revolving disk, and the edge cfa wheel,Y, (of the form shown in fig. 3,) is caused to bear firmly against the outside and lower edge of the auge z', which is thus bent inwards, as shown in the drawing. As the flange z' is forced against the lange e the latter is bent to a position parallel to the ilange z', the two flanges beingbrought into such intimate Contact that even' in the absence of solder the contents of the can cannot escape at the joint. So 'secure is the cap B that it cannot be detached by any ordinary rough usage to which the vessel maybe subjected.

When, however, it is desired to remove the cap, the edge of a chisel or other like` instrument is introduced ,v beneath the ange e' so as to force the cap upwards. The can may be held stationary while the wheel revolves round the anges, and in some instances the flanges may be compressed between two wheels, y y, the latter bearing on the edge of the depression in the top of the cap, as shown in iig. 3. i

The above-described mode of lsealing cans is cheap, expeditious, and entirely obviates the necessity of using solder or cement.

I claim as my invention, and desire to secure by Letters Patent- Y The can A, with its opening x, and flange e, and the cap B, with its flange z', when the two Vare fitted and secured together, as described. l

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

DANIEL W. PEPPER.
